PHONOGRAPH-HORN SUPPORT.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed March 25, 1907. Serial No. 364,400.

I To all whom it may concern:

Be it known that we, OTTO L. ENDREs and REIN- HOLD PIETSCII, of Utica,in the county of Oneida and State of New York, have invented certain newand useful Improvements in Phonograph-Horn Supports; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

The object of our invention is to provide a support of a substantialconstruction for the horns for phonographs, said support being easilyand conveniently applied to the machine or case, and arrangedforsuitable adjustments to adapt it to uses for various makes ofmachines and various sizes and arrangements of the horn.

Figure l shows a plan view of the horn support, which is the subject ofthis invention, applied to the machine and in use in the usual manner.Fig. 2 is a side elevalieu of the base of the machine, together with thesupport before referred to. Fig. 3 is another elevation from a point ofview taken at right angles to that shown in Fig. 2. Fig. 4 shows detailsof a nut and wrench for securing the attachments to the machine case, inplan view. Fig. 5 shows details of this construction partially insection. Fig. 6 shows details in section, and Fig. '7 same details inelevation, of an adjustable joint employed in the support.

Referring to the reference letters and figures in a more particulardescription, 1 indicates the base ofa phonograph, which base is usuallyprovided with slots 2 to receive a removable box cover. in the ordinarymanner.

3 is an arm, which is adapted to be secured to the base by a hook 4having a screw-threaded shank, said hook adapted to be passed throughone of the slots 2, its shank passing through the inner end of arm 3 andreceiving the nut 5 and the wrench 6. The lower portion of the nut 5 iscylindrical, while the upper portion is octangular, or of any othersuitable angular form. The wrench 6 is provided with a round opening toreceive the lower end of the nut 5, and also with an octangularorsuitable formed recesses to receive the angular portion of the nut 5.When the wrench is in its elevated position, as shown in Fig. 5 the nutmay be rotated by the wrench and when in its lower position the wrenchmay be rotated freely on the lower end of the nut. By this arrangement,means is provided for applying sufficient force to the nut 5, which isordinarily located in such proximity to the end of the phonographmechanism as to make it impossible to use a crank nut.

The arm 3 is adapted to extend beyond the front of the base 1, as shownparticularly in Fig. 3, and in its projecting end is a vertical eye 3,which receives the post 7. The post 7 is preferably provided on itslower end with a rubber tip 7 adapted to rest on the top of a table asT, on which the machine may set. At the upper end the post 7 is providedwith a joint member 8, which receives the joint member 9 of the swingingarm 10, the two being pivoted together on a pivot 9. The joint member 9is provided with a segment of cog teeth, as shown in Fig. 6, adapted toengage with the laterally sliding toothed nut 8 provided in a chamber inthe part 8, the nut 8 being moved by the thumb screw 8". The arm 10 ispreferably made tubular and receives the telescoping extension 11, fromthe outer end of which the phonograph horn A is adapted to be suspended.The lower end of the post 7 resting on the table top or other supportingsurface for the phonograph base 1 gives stability to the horn supportand obviates a tendency to overturn the phonograph machine base, whichis a common objection where horns of large dimensions are employed. Byrotating the post 7 in the eye 3, the arm 10 with its extension 11 canbe given such an angular position with reference to the base 1 as willsupport the horn in the desired angle with reference to the base.

The elevation of the horn can be changed or adjusted by manipulating thethumb screw 8. The several parts of the horn support may be readilytaken apart, and when thus taken apart can be placed in a compactbundle, which is not objectionable to handle or carry and quite afeature in a device of this kind.

What we claim as new and desire to secure by Letters Patent is:

1. The combination with the supporting arm, post, and swinging arm of ahorn support of the attaching device consisting of the screw-threadedhook 4, the nut 5 having a cylindrical lower portion and an angular headportion and the wrench G permanently mounted thereon and adapted to bemoved laterally on the nut to engage and disengage the angular portion,substantially as set forth.

2. The combination in a horn support for phonographs of the uprightpost, an adjustable arm hinged to the upper end of the post, and anadjusting mechanism therefor consisting of a toothed segment attached tothe adjustable arm and a laterally movable toothed nut incloscd in thejoint and engaging with said segment, and a screw for moving the nut,substantially as set forth.

In witness whereof, we have allixed our signature, in presence of twowitnesses, this 18th day of March, 1907.
